50 years of glaciers changing, disappearing, in Montana

The warming climate has dramatically reduced the size of 39 glaciers in Montana since 1966, some by as much as 85 percent, according to data released by the U.S. Geological Survey and Portland State University. On average, the glaciers have reduced by 39 percent and only 26 glaciers are now larger than 25 acres, which is used as a guideline for deciding if bodies of ice are large enough to be considered glaciers.

The data include scientific information for the 37 named glaciers in Glacier National Park and two glaciers on U.S. Forest Service land. The retreat of glaciers is significant in Montana because of the impact shrinking glaciers can have on tourism, as well as being a visual indicator of mountain ecosystem change in the northern Rocky Mountains…

“While the shrinkage in Montana is more severe than some other places in the U.S., it is in line with trends that have been happening on a global scale,” geologist Andrew Fountain said…

This information is part of a larger, ongoing USGS glacier study of glaciers in Montana, Alaska and Washington to document mass balance measurements that estimate whether the total amount of ice is increasing or decreasing at a particular glacier. This information helps scientists understand the impact of large scale climate patterns on glaciers in distinctly different mountain environments.

Some of the glaciers the park is named for are now too small to qualify as glaciers. That’s OK. The brains in some of the politicians we’ve elected to serve the people – are now too small to do much more than parrot statements programmed in by major campaign donors and other political scum.

They’re the individuals chosen in our democratic republic charged with solving problems on this scale.

    The melting of the mighty Aletsch glacier is causing the land attached to it to slip at a dramatic rate, according to new research by the Federal Technology Institute in Zurich (ETH Zurich).
    Researchers have used a new dataset to confirm a direct link between the melting of Europe’s longest iceflow in the Swiss canton of Valais and the slippage of the adjoining Moosfluh slope at a rate of around 30 centimetres a year.
    The land at Moosfluh has been moving for years, and last September the cablecar was forced to stop operations due to the movement of the ground.
    Now, a long-standing project by scientists at ETH Zurich has proved the slippage is connected directly to the melting of the glacier “and thus to climate change”, the university said in a statement. https://www.thelocal.ch/20170124/swiss-scientists-melting-glacier-makes-the-earth-move
